  • Patent number: 7373960
    Abstract: The invention provides a brush cutter and chipper that attaches to the end of an articulating arm or boom on equipment. The cutter may utilize existing hydraulic power and controls. The cutter includes a housing with external feed assembly that feeds material through a gate to an internal cutting assembly. The feed assembly has a tensioned upper roller that may move arcuately and a stationary lower roller. The rollers preferably rotate oppositely and each has peripheral cleats to facilitate feeding. The housing mounts an internal rotating drum that may be rotationally linked with the rollers. The drum has a cutting surface, which may be a peripherally wound toothed chain, that cuts entering materials smaller pieces. The drum rotates against the bottom side of the fed material to insure that the material is cut into small pieces. The small pieces exit through a chute at the bottom of the housing.
